STEAM PUMPlNG-ENGINE.

T LZZ 1li/'hom if may concern.: n

p Be it known that I, FRANK S'rEINMANN,of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Steam Pumping-Engines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which" Figure I is a side elevation of my improved engine, shown in connection with a pump. Fig. II is a vertical longitudinal section of the engine, takenon line II II, Fig. VI. "Fig, III is a similar view taken on line III III, Fig. VI. Fig. IV is a top" view with. the valve'- chest removed. Fig. V is a similar view with the valve also removed. Fig. VI is a vertical transverse section taken on line VI VI, Fig. II. Fig. VII is au enlarged perspective view of the D-valve. Fig. .VIII is an enlarged perspective view of the auxiliary valve. Fig. IX is a vertical longitudinal section taken on line IX IX, Fig. X. Fig. X is avertical transk verse section taken on line X X, Fig. XI. Fig. XI is a vertical longitudinal section taken on line XI XI, Fig. X. Fig. XII is a vertical transverse section taken on line XII XII, Fig. XI. Fig. XIII is a vertical transverse section taken on line XIII XIII, Fig. I. Fig. XIV is a vertical transverse section taken on line XIV XIV, Fig. I. Fig. iXV is an enlarged detail elevation illustrating the mechanism for mov-` ing the auxiliary valve.

My invention relates to certain improvements in steam pumpingengines; and my invention consists in features of novelty here inafter fully described, and pointed out in the claims.

' Referring tothe drawings, 'l represents thel main cylinder of the engine, within which is located a piston, 2, having a rod, In the cylinder l are formed the supply-ports 4 `5 and the exhaust-port 6. The ports et and 5 are controlled by a D-valve, 7, located in a chamber, 8. Above the chamber- 8 and. D- valve 7 is an auxiliary piston, 9, located in a cylinder or chamber, l0. Between the cylinders or chambers l and l0 the chamber 8 is located, and in this chamber S is an auxiliary valve, l1. The valve 7 is connected to the piston 9, as shown in` Fig. III, the piston having a central opening, l2, to receive upseria No; 283,266. (No modem wardly-extending wings 13, formed upon the' valve 7. (See Figs. III and VII.) The wings tit snugly in the opening l2, so that the valve 7 will be moved back and forth with the pis" ton 9; but at the same time itis allowed to move downwardly on its seat, so that it ali ways fits snugly, regardless of the amount of wear it may receive. The chamber 8 communicates at its opposite ends with the cylinder IO through ports 14: 15, which are controlled by the auxiliary valve l l. The valve ll has a stem, 16, which extends to near the center of the connecting-frame 17 between the engine and pump, (see, Fig. I,) where it is connected to an arm, 18, as shown at 19.

cured to the upper end of a standard, 2l, mounted on the frame l'. (See Figs. I, XIV, and XV.) On the shaft or spindle 2O is also a level1 or arm, 22, the lower end of which is `provided with a slot,23, to receive a pin, 24,

and forces the piston 9 and valve 7 over into the position shown in Fig. II. This exposes The u arm l8 is pivoted on a shaft or spindle,20, se-

the port 4; and the steam passes through the port Il into the cylinder l, behind thel piston 2, and forces the piston in the direction shown by the arrows, Figs. II and III. As the pis-'g ton 2 reaches the limit of its movement inthis`r direction, the lever 22 comes against the lug 25 on the arm -18 and swings the arm in theY direction indicated by the arrows, Fig. I. This moves the auxiliary valve ll in the direction indicated by the arrows, Figs. II and III, which closes the port 14. and opens the'v port l5, thus allowing the steam to pass through the port l5 .into the cylinder l0 and force the auxiliary piston 9 in the opposite direction to that in which it was moved by the steam passing' through the port 14. This shifts the D-valve 7, closing the port 4 and` opening the port 5 to live steam, which then,

. the usual manner.

, tion goes on continuously. The valve 11 is provided with ports 14%, (see Figs. II and `VIII,) `which form communications between the ports 14 and 15 above and below the valve. As the piston 9 is moving in the direction indicated by the arrows, Fig. II, the steam escapes through the port 15 into the port 6, as indicated by the arrows on the right-hand side of Fig. III. The arm 18 has a slot, 18%, which receives a pin, 21%, on the standard 21. The object of this slot and pin is to prevent the valve being carried too far in either direction by its momentum. The pin allows the valve to be moved in either direction as far as the piston 2 carries it, but still prevents the momentum of the valve carrying it beyond its place.

The construction of the pump is shown in Figs. IX toL XII, inclusive.

30 represents a piston secured to the rod 3. It works in a cylinder, 31, located within a housing, 32, and communicating at its respective ends with water-chambers 33 34.

35 35% represent water-chambers between the cylinder and housing, with which communicates an inlet-port, 36, and an outletport, 37. (See Fig. IX.) The heads 38 of the cylinder are provided with valves 39 and 40, which control the passage of the water, the valves 39 permitting the passage of the water from the lower chamber, 35, into the chambers 33 34, and the valves 40 permitting the passage of the water from the chambers 33 34 into the chamber 35%. Each of the valves 39 (see Fig. XI) seats against a ring, 41, connected by arms 42 (see Figs. XI vand XII) to a central stem, 43, which is provided with a head, 44, that fits in an opening, 45, in the head of the cylinder 31.

The head 44 isprovided with a socket to receive a wrench, and by turning it the ring 41 is unscrewed and the valve can be thus the valve and a disk, 47, on the stem.

' dicated by the arrows in Fig. IX, the water water in front of the piston passes from the chamber 33 through the valve 40 into the chamber 35%. The upper ends of the ports 37 are provided with openings 60 and an air= chamber, 61. There may be more than one of the openings 60, and, if so, all but one will be closed by plugs 62. The discharge-pipe is connected to any one of these openings 60, as desired, and if it is desired to use the machine inV avert-ical position the air-chamber may be screwed into one of the openings 60 and the Water discharged through the opening which the air-chamber occupies in Fig. IX. (See dotted lines, Fig. I.)

In this application I have shown and described in connection with my engine an ima proved pump; but Ihave not claimed the same herein, as such forms the subject-matter of my application, Serial No. 293,698, filed December 15, 1888.

I claim as my invention 1. The combination of the main cylinder pro- Vvided with a piston and receiving-ports, 4 and 5, and exhaust-ports 6, an auxiliary cylinder located over the main cylinder and having ports 14 15 communicating therewith, an auxiliary piston connected to the valve of the main cylinder, an auxiliary valve for controlling the ports of said auxiliary cylinder, having the exhaust-ports 14% extending therethrough, adapted to place the exhaust 6 and the ports 14 15 in communication, and mechanism connecting the rod of the main piston to the stem of the auxiliary valve, substantially as and for the purpose set forth.

2. The combination of the main cylinder provided with apiston and receiving and exhaust ports, an auxiliary cylinder located over the main cylinder, an auxiliary piston, avalve for controlling the ports of the main cylinder connected to said auxiliary piston, an auxiliary valve for controlling the ports of the auxilfv iary cylinder, and a connection between they valve-stem and piston-rod of the main cylinder, consisting of a pivoted arm to which said stem is connected and which is provided with lugs and a slot, a lever connected to said piston-rodVa standard to which said arm and lever are connected, and a pin on the standard fitting in a slot in said arm., substantially as and for the purpose set forth.
